CROSS-REFERENCES TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/655,571, filed Jul. 20, 2017, which claims the benefit of U.S. Provisional Application No. 62/364,695, filed Jul. 20, 2016, all the disclosures of which are incorporated by reference herein in their entirety.

BACKGROUND

Many products are distributed in bags and bulk packaging formed of paper, plastic or other substrates. Bulk packaging containing solid dry particulate or liquids must often be permanently opened. For example, some bags or boxes must be cut or torn open in order to pour out the product they contain. Others may include an integrated closable pouring region—usually along the top of the packaging. In either case, the packaging is designed with a one-use seal. Once opened, the package cannot be resealed. Often it is desirable to remove only a portion of the contents for immediate use. The remainder must then be disposed of, allowed to sit unsealed, or transferred to secondary storage containers that occupy substantial storage space.

SUMMARY

Embodiments of the present disclosure aim to address the problem of single-use containers and reducing waste or the need for secondary storage containers. As will be described in more detail below, the disclosed technology is directed to methods and apparatus for a reusable, sealable dispensing system that may be attached to bulk packaging via an adhesive element or coupler.

The dispensing system includes a spout. The spout in some embodiments includes a flanged end configured to attach to a two-sided coupler covered with an adhesive selected to make the spout removable by hand. When the package has been emptied, the spout may be removed and attached to a new package or container with a new adhesive element or coupler.

The spout also has an end designed to be closed and/or sealed shut when not in use. Various mechanisms for closing and/or sealing the end are contemplated, as are differing cross-sectional shapes for the spout. To pour the contents of the packaging, a hole is created, formed, cut or otherwise provided in the packaging container. Creation of a hole is considered at various points during the spout connection process. When attached to bulk packaging, the system creates a reusable and optionally resealable, space-efficient storage solution.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appended drawings, where like numerals reference like elements, is intended as a description of various embodiments of the disclosed subject matter and is not intended to represent the only embodiments. Each embodiment described in this disclosure is provided merely as an example or illustration and should not be construed as preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the claimed subject matter to the precise forms disclosed.

Turning now to FIG. 1, there is shown a representative embodiment of a reusable dispensing system, generally designated 20, formed in accordance with an aspect of the present disclosure. As shown in FIG. 1, the reusable dispensing system 20 is suitable for use with a bulk packaging container BP. As will be appreciated by the following disclosure, the reusable dispensing system 20 is suitable for use by a consumer to assist in dispensing or pouring a solid dry particulate product contained in the bulk packaging container BP while maintaining the freshness of the product and minimizing spillage. Products include, but are not limited to animal food, fertilizers, chemicals, and other dry, solid particulate material suitable for being housed in a bag or other bulk packaging, etc.

FIGS. 2A and 2B are exploded views of a representative embodiment of the reusable dispensing system 20. As shown in FIG. 2, the reusable dispensing system 20 comprises a spout 30, a coupler 40 configured to detachably connect the spout 30 to the bulk packaging container BP, and a closure or cap 50. Of course, in some embodiments, the coupler can be configured to couple the spout 30 to the bulk packaging container BP in a more permanent manner for single use purposes.

In the embodiment shown, the spout 30 includes a body with circular cross section and a flanged base 32. However, it will be appreciated that other geometries, such as ovaloid or rectangular cross-sections, may be practiced with embodiments of the present disclosure. In each case, the spout 30 defines openings 34, 36 at its upper and lower ends, respectively. The openings 34, 36 are interconnected via conduit 38.

The spout 30 is formed from either petro-based or bio-based plastics that have been approved for food contact by the FDA, but alternatives such as steel, aluminum, or any other material suitable for contact with the items contained in bulk packaging may be used. In some embodiments, the spout can include materials, such as polylactic acid (PLA), bio-derived polyethylene, cellulose acetate, polyethylene terephthalate (PET), polypropylene (PP), High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and polycarbonate (PC).

As briefly stated above, the spout 30 is attached to the bulk packaging container BP via the coupler 40. The coupler 40 in some embodiments is shaped and sized to match the outward facing surface of the flange 32. In the embodiment shown, the coupler 40 is formed as a ring. The inner hole 42 defined by the ring is sized and configured to cooperate with the lower opening 36 of the spout 30. The coupler 40 is made from a suitable material, such as rubber, a polymer foam, or plastic, to name just a few. In some embodiments, the top and bottom surfaces 44 and 48 of the coupler 40 or section thereof are coated with an adhesive 48. In other embodiments, the coupler 40 may additionally or alternatively have inherently adhesive properties. In some embodiments, the adhesive is selected from a class of removable adhesives. In some embodiments, the removable adhesive is R3500 removable acrylic adhesive sold by 3M™. In some embodiments, the coupler is formed out of a removable adhesive putty, such as Blu-Tack™, a removable acrylic adhesive double-sided adhesive tape, etc. In some embodiments, the surfaces of the coupler include backing paper that is removed prior to use.

Turning now to FIG. 3, the spout 30 is connected to the bulk packaging container BP by the coupler 40. When ready for use, one side of the coupler 40 is attached to the flanged base 32 of spout 30 via adhesive 48 a and the other side of the coupler 40 is attached via adhesive 48 b to the bulk packaging container BP. The adhesive 48 a connecting spout 30 to the coupler 40 is selected such that spout 30 may be removed from the bulk packaging container BP by hand. After spout 30 has been removed, a new bulk packaging container may be selected, and a new coupler 40 can be employed to attach the spout 30 to the new bulk packaging container for continued use. In some embodiments the same adhesive material is used on both the spout and package sides of the coupler 40. In other embodiments, different adhesives with different adhesive properties are used to connect to the spout and the package.

Various forms of closing and/or sealing the spout 30 once connected to the bulk packaging container BP are contemplated for practice with embodiments of the present disclosure. In one embodiment, the end of the spout 30 opposite the flanged base 32 includes external threads 62, which are configured to cooperatively connect with internal threads 64 of the cap 50. As such, the cap 50 and threads 62, 64 combine to form one embodiment of a closure mechanism. Other embodiments of closure mechanisms are contemplated to be practiced with embodiments of the present disclosure. For example, a closure mechanism can be provided that comprises a spout with internal threads and a threaded plug. To close the spout, the plug is inserted into the opening of the spout and tightened. In other embodiment, a closure mechanism composed of only a plug to be inserted into the end of the spout can be utilized. The plug in this embodiment can be made of a material such as rubber, plastic, metal, or any other material suitable for forming a seal and a fiction fit with the opening of the spout. In other embodiments, a closure mechanism is formed by a cap with a lip or other form of internal ridge that snaps onto (or over, or into) the end of the spout.

A method for assembling the reusable dispensing system 20 onto the bulk packaging container BP will now be described with reference to FIGS. 1, 2A-2B, and 3. It will be appreciated that the order in which the elements of the reusable dispensing system 20 are attached may vary. Returning to FIG. 3, the coupling 30 may initially be attached to either the spout 30 or the bulk packaging container BP before being used to mate the two. In the embodiment shown in FIG. 3, the coupler 40 is first attached to the bulk packaging container BP via adhesive 42 b. If the coupler 40 is first attached to the bulk packaging container BP it may be used as a guide or template to assist users in the creation of a hole 70.

For example, hole 70 is to be made in the bulk packaging container BP before the contents of the bulk packaging container BP may be extracted through the spout 30. In some embodiments, the hole can be cut out via utility knife or other sharp bladed device. The hole 70 may be made before the coupler 40 is attached to the bulk packaging container BP, after the coupler 40 is attached to the bulk packaging container BP but before the spout 30 is attached to the coupler 40, or after both the coupler 40 and spout 30 have been attached to the bulk packaging container BP.

In the embodiment shown in FIG. 3, the coupler 40 is first attached to the bulk packaging container BP and then the hole 70 is formed in the bulk packaging container BP. Next, the base flange 32 of the spout 30 is aligned with and pressed down against the coupler 40, affixing the spout 30 to the bulk packaging container BP. Once attached, the spout 30 can be used to selectively empty the contents of the bulk packaging container BP. Cap 50 can be used to close and seal the bulk packaging container BP between uses.

After the bulk packaging container BP has been emptied, the spout 30 may be removed by hand. In one embodiment, the spout 30 separates from the coupler 40 when pulled therefrom while the coupler 40 remains attached to the now-empty packaging container. A new coupler 40 may then be used to attach the spout 30 to a new bulk packaging container.

Various forms of bulk packaging containers are suitable for use with the removable spout. For example, the bulk packaging containers include without limitation: boxes, bags, or other means of storing solid particulate or liquid goods. The containers may be made of pulp, paper, plastic, metal, or other materials typical of bulk storage.

The disclosed reusable dispensing system eliminates the need to tear open a bag or packaged product, provides a convenient solution to reseal the package, and precludes the need for secondary storage containers. All the user needs to do is remove the cap and pour the material from the bulk packaging or bag through the pouring spout of the flanged base after the reusable pouring spout is attached in the manner described above. Due to the uniquely tested and identified adhesion properties of the adhesive ring, the flanged based is simply and easily removed by hand once the once the bulk contents have been depleted. The flange base is then ready to be reused in conjunction with a new coupler.
